Pinout
5| Pin | Name | Functions | Notes |
|---|---|---|---|
| Vcc | Power | POWER | This is the power pin. To power the board, give it the same power as the logic level of your microcontroller - e.g., for a 5V micro like Arduino, use 5V. |
| GND | Ground | GND | Common ground for power and logic. |
| SCL | I2C Clock | I2C | Connect to your microcontroller's I2C clock line. The logic level is the same as Vcc, with a 10K pullup already on it. |
| SDA | I2C Data | I2C | Connect to your microcontroller's I2C data line. The logic level is the same as Vcc, with a 10K pullup already on it. |
| A0 and A1 | Address Select Pins | GPIO | These pins set the bottom two bits of the I2C address. Connect them to VDD to set the address, or cut the solder jumper and wire them directly. |
